Abstract: The present invention relates to a grip tape for ball game rackets having a conical or trapezoidal base shape in the longitudinal direction or a length and a width, wherein the width varies at least along an essential portion of the length. The present invention also relates to a replacement grip tape including the features of a grip tape of the invention, and a process for producing a grip tape of the invention. Moreover, the present invention also relates to a grip for a ball game racket including a portion facing the head region of the ball game racket and having a first cross-section and a portion facing the end of the ball game racket and having a widening cross-section for holding the grip, as well as the combination of grip and grip tape.

Abstract: A racket for ball games may include a frame which is formed by a frame profile or a hollow profile and has a racket head and a handle portion connected thereto preferably via a heart region. Two indentations that are symmetrical relative to the longitudinal axis of the racket may be provided in the heart region of the frame. A vibrating device may be arranged in each of the two indentations. The vibrating means of the racket may preferably be effective for vibrations having at least two vibration modes or degrees of freedom. Additionally or alternatively, a racket for ball games may include a frame which forms a head region for receiving strings and a handle portion for holding the racket. The frame may include one respective inwardly-facing C-profile in at least two segments of the head region.

Abstract: The racket (2) for ball games of the present invention comprises a frame which is formed by a frame profile or a hollow profile and has a racket head and a handle portion connected thereto preferably via a heart region. Two indentations (12) that are symmetrical relative to the longitudinal axis of the racket are provided in the heart region of the frame. A vibrating device (20) is arranged in each of the two indentations. The vibrating means of the racket of the present invention are preferably effective for vibrations having at least two vibration modes or degrees of freedom. The invention further relates to a racket for ball games comprising a frame which forms a head region for receiving strings and a handle portion for holding the racket, wherein the frame comprises one respective inwardly-facing C-profile in at least two segments of the head region.

Abstract: The invention relates to the antifelt finishing of wool in which the wool is (a) first exposed to a plasma in a corona treatment and (b) subsequently treated with an aqueous dispersion of self-dispersing isocyanates.

Abstract: A spiral displacement machine has a displacer with a central disk and spiral vanes on both sides arranged to revolve eccentrically in a housing with spiral vanes to provide working chambers which rotate spirally. The beginning and end regions of the vanes are angularly offset so that the working chambers do not open or close simultaneously.

Abstract: An apparatus for cultivating immobilized micro-organisms consisting of a fluidized bed reactor with fittings for gassing and a retainer system for the immobilized biocatalysts. The fluidized bed reactor is characterized in that the fittings for gassing consist of several segments with gas outlets arranged on the base of the fluidized bed reactor, which admit gas alternately or cyclically. A central gas outflow opening, pointing upwards, can be provided in the fluidized bed reactor as a further gassing unit. The method of operating the fluidized bed is characterized in that circulating gassing occurs in the reactor by means of sequential opening of the gas inflow openings of the segment-shaped fittings. In addition, switches may occur from the central gassing unit to gassing by means of the segment-shaped fittings or vice-versa.

Abstract: In the embodiment of the invention described in the specification, a drive assembly for an eccentrically driven mass has a drive shaft which drives the mass by a first eccentric device and a secondary shaft, driven synchronously with the drive shaft, which drives a second eccentric device spaced from the first eccentric device so as to guide the mass in a constrained manner. The connection between the second eccentric device and the mass includes a resilient mounting. In order to avoid, or at least reduce, sinusoidally varying stresses imposed on the resilient mounting during operation as a result of deflection of the drive shaft, the eccentricity of the second eccentric device is larger than the eccentricity of the first eccentric device by at least a portion of the magnitude of the maximum deflection of the drive shaft in the region of the mass occurring during operation.

Abstract: A displacement machine for compressible media, with at least one displacement chamber arranged in a stationary housing and rendered in the manner of a groove extending with a spiral shape, and with a band-shaped or tongue-shaped displacement body associated with each displacement chamber and likewise rendered in spiral shape is described. The displacement body is held on a discoid rotor, which can be driven eccentrically relative to the housing, in such a manner that during operation, each of its outside wall points performs a circular movement bounded by the peripheral walls of the displacement chamber. The curvature of the displacement body relative to the curvature of the displacement chamber is dimensioned such that the displacement body nearly comes in contact with the radially inner and outer peripheral walls of the displacement chamber.
